Main article: Comparison function

Greater than (>) is a comparison function which tests whether the left argument is tolerantly greater than and not equal to the right argument, returning 1 if this is the case and 0 otherwise. It is the negation of Less than or Equal to ().

Boolean function

When the arguments to Greater than are Boolean, it is the material nonimplication Boolean function, also known as the NIMPLY gate:

> 0 1
0 0 0
1 1 0

In the context of logic, it can be read as but not.
